Boston Police and Park Rangers were present for part of 4/20 afternoon on the hill.
But they wisely decided by the magic time of 4:20 to let the crowd enjoy their high holiday.
No citations were issued, no arrests were made. Nobody was searched and asked not to photograph the Police or Park Rangers.
A couple of hundred people lit up cannabis at 4:20pm.
WBUR-Boston and the Boston Phoenix were two of the largest local media in attendance covering the "spontaneous" gathering.
